To all whom it may concern:

Be it known t at I, SYDNEY Cnosam, a subject of the King of GreatBritain, residing in New Barnet, England, (whose post-ofiice address isThe Chestnuts, New Barnet, in the county of Herts, England,) haveinvented certain new and useful Improvements in or Connected withApparatus for Vaporizing Oil, of which the following is a specification.

This invention relates to apparatus used in conjunction with oil fuelfurnaces, for

the atomizing and vaporization of the fuel simultaneously with itsmixture with air which apparatus is of the kind wherein the liquid fuelis atomized by means of a re volving atomizing device and \an intimatemixture of the air and oil, in any desired proportions, is obtainedprior'to its injection into a furnace for complete combu'stion therein.7

It consists in'i rovements according to or effecting the mechanicalatomizing, simultaneously with the carbureting and va for. providing theeed of oil and for supplying the air to the atomizing device areoperatively connected and driven from a single source of power, whilemeans are provided for varying the height of the longitudinal axis ofthe apparatus, for altering the direction of the vaporized oil issuingfrom the delivering end of the apparatus and for periodically rotatingthe carbureting tubes employed.

The improved apparatus may be mounted onwheels to be of a portablenature.

The invention will be described with reference to the accompanyingdiagrammatic drawings, in which- Figurel is a side elevation of anapparatus constructed according to this invention; Fig. 2 is anelevation of the reverse side of the ap aratus; Fig. 3 is a furnace endview of t e apparatus; Fig. 4 is the front view of the apparatus; Fig. 5is a artial section through A-B marked on Figs. 1 and 2; Fig. 6 shows apart of the apparatus in section through CD on Fig. 3; and Fig. 7 is asectional detail of a conical atomizing device.

An oil vaporizing apparatus constructed according to my inventioncomprises a -chamber E of suitable shape and of cast iron, wrought iron,mild steel, or other suitable metal. Within the chamber is' arorizing ofthe oil and ranged one or more pipes H for a purpose hereinafterreferred to; This chamber is lined within by fire bricks, ganister,mixtures of magnesium lime stone and carbon, or other refractorysubstances, to prevent the radiation of heat andincidentally the gradualoxidation of the metal case. The chamber may be further protected on theexterior by a layer of non-conducting material such as infusorial earth,slag wool, or other good non-conducting materials, covered in and heldin position by sheets of charcoal iron, the object of which is also toprevent radiation of heat.

,Upon the front end of the apparatus is bolted an air box I of suitableform. To the bottom of this air box is attached an .iris diaphragm airregulator which directs the incoming air always axially, that is to saycentrally; to this iris diaphragm is attached outside the air box a wormwheel Z adapted to be actuated by a worm upon a shaft 2 to whichmechanical movement is communicated from the shaft of an oil-inletregulator to be subsequently described. The pipe upon which this wormwheel is fixed has upon it a bellows O fitted with a slipping fit sothat the worm Wheel may be revolved without revolving the bellows belowit, the bellows is made of leather or other suitable material, and isconnected to the fan M for shape for instance circular as shown, are Ithe two pipes H into which the air is blown by fan M. The pipes H areattached to the ends'of chamber E in glands e in such a manner that theymay be rotated in those ends, ball bearings being provided if neces-vsary. Into each of these pipes H is passed a small pipe S for conveyingthe oil to be atomized and upon the ends of these small pipes and withinthe larger pipes H are cones S furnished upon their extreme faces orends with sharp cutting edges as shown in Fig. 7 Alternatively thesecones may be similar to those described in my British specification No.18917 of 1912 and in my co-pending nited States patent applica-' tionSerial No. 7 58515 filed April 29, 1913.

The cone carrying 'pipes' S pass through the outer wall of the air box Ito its exterior and enter chambers R which serve as stufiing boxes. Atright angles to the pipes S is a ranged so that the flames may 7 burnerflame may be shaft 9 carried by bearings constituted by The oilvispassed into the chambers R by flexible tubes 2', the oilvbeing aspiratedby' pumps Q through oil regulators P and forced into the chambers,thence through the pipes S which are adapted to be turned upon ballbearings at high speed.

By reason of the high speed at which these pipes turn, the oil when itreaches the edge of a cone is cut to ieces and thrown out intothe'larger pipe where it is mixed with the air therein and becomes inphysical appearance like a white fogand, assisted by the heat from theflame be projected into the chamber E, is vaporized. I The regulated byany suitable means.

The flame acting on the exterior of the two pipes in which the cones arerevolving causes the vaporization of the oil, While the carboninonoxidand othergases are projected with a whirling motion into the furnaceWhere they take up sutiicient oxygen to produce complete combustion ofthe fuel.

The large chamber E is provided with short chimneys F F to allow thesurplus heat to pass oii and to provide a current of air for the burner.

The oil and air regulator, which is the subject of my Britishspecification No. 254510 of 1911 and is fully described therein ispreferably used in apparatus constructed 3 0 cording to the presentinvention, for the purpose of delivering the oil and air through therespective devices in such a way that the turning of the handle upon theoil regulator fitted with suitable transmission gear will cause thedelivery H in the chamber E, constituting a carbureter, the properproportion of air that is required to combine with the oil, and thegears may be changed according to whether it is desired to produce a'reduclng flame or an oxidizing flame in the furnace, and may be of anyratio.

The chamber E and the associated parts are carried by a frame orcarriage K provided with wheels L, L of any convenientsize. On the frameK are bearings J which can be adjusted as to height by means of thescrew device J, so that the height of the axis of the chamber E can bevaried. At the furnaceend of the frame is arranged a suitable screwraising or lowering device U which can be-operated to lift or lower thefurnace end of chamber E turning about the bearing J. By operating thedevice J,

the chamber E and associated parts may be of a burner N ar- "turned by acapstan wheel T to the pipes bodily raised or lowered, and by Workingdevice U the discharge end of the chamber may be brought intoregistration with the part of the furnace with which it is to cooperate.

The pivoting or tilting features of the apparatus are very useful, forthe reason that they permit the combined gases to be injected into afurnace or combustion chamher, with which the apparatus is tocoiiperate, at any desired height, andeither downward upon any metalunder treatment, or upward in the case of furnaces of a certainconstruction The mechanism of my apparatus may be driven in any suitablemanner as for instance by electricity as illustrated in the drawings,but in any case, whatever the motor. the air fan only is driven by it,the power required for the other parts of the mechanism being taken fromthe extended shaft m of-the fan, @fi this shaft is carried a chain orbelt a to a wheel V on the shaft g. The fan M and the prime mover, suchas'motor a, may be mounted on a separate carriage M. connected orcoupled in suitable manner to the frame K. Upon shaft 9' are keyedwheels-W connected by belts or chains vto gears X on counter-shaftsoperatively connected to wheels Y which in turn communicate their motionto the pumps (,2 aspirating the oil through the oil regulators P anddelivering it under pres-' sure to the stufiing boxes lit.

v The pipes H passing through the cham-=' ber E and in which the oil isatomized as it leaves the cones, have each fixed upon them, by set pinsor keys, a worm wheel Tactu ated by a 'worm. T on a shaft T which is IBy these means the pipes may be? periodically turned through any desiredangle, the object of this being to present a new surface to the heat inorder to give the pipes a longer life than what they wbuld have if thenecessary heat were allowed to impinge on the samesurface of the pipealways: the burning through of the pipes is thus delayed.

In the furnace associated with the apparatus of this invention theatomizedmim ture is completely burnt to :CO which passes out of theuptake into the atmosphere. I

For firing boilers on board ships, the ap paratus may be carried uponeither low wheels or the wheels may be omitted in order to accommodateitself to the openings of the fire boxes in cases the chamber E-"ispreferably made smaller in diameter and contains only one vaporizer oratomizing tube. For marine purposes it is not necessary for the fans t0-be attached to the frame-of the apparatus for they may be placed in anyconvenient position. v
